i386.md has

;; The special asm out single letter directives following a '%' are:
;; 'z' mov%z1 would be movl, movw, or movb depending on the mode of
;;     operands[1].

But what %z really does is

;; 'z' print the instruction suffix for the size of the current
;;     memory operand on x87 instructions and register operand on
;;     integer instructions.

When people are reading gcc source, they will get wrong information.
